At present, most metal frame antenna solutions are realized by slitting on the metal back shell, and the biggest drawback of this design is that when the call state is reached, the hand touches the gap and causes a signal. The serious decline ("the grip of death"). The back seam is generally symmetrical on the left and right sides, and there are two main types of "dead grip" grips: 1. Hold one side seam and the other side is not held (in most cases); 2. Both sides are sewn. At present, the commonly used antenna design scheme is a single antenna at the bottom, and the radiation arm is generally unidirectional. When the slit on one side of the radiation arm is held and the other side seam is still open, the antenna is also clamped, which greatly increases the number of antennas. The probability of a grip of death.

The following uses a mobile phone as an example for description. In this embodiment, the antenna includes the basic structure of the antenna commonly used in the prior art, that is, the feeding, the radiating unit, and the grounding. The radiating unit of the antenna provided in this embodiment is a part of the metal casing of the mobile phone (the metal of the mobile phone) The outer casing is cut open, a part of which acts as a radiating element of the antenna).
如图1所示，图1示出了本发明实施例提供的天线结构。As shown in FIG. 1, FIG. 1 shows an antenna structure provided by an embodiment of the present invention.
本发明实施例提供了一种移动终端的天线，该天线采用馈电点101及地的混合切换原理，具体的，该天线包括：辐射单元20、馈电点101、地以及 连接辐射单元20及地的接地线30；还包括与辐射单元20连接的至少两个连接线；其中，至少两个连接线中的一个连接线可选择性的切换到馈电点101或悬空状态，其余的连接线中的至少一个连接线可在馈电点101及地之间选择性连接；且在至少两个连接线在选择性连接时，至少两个连接线中仅有一条连接线与馈电点101连接。The embodiment of the present invention provides an antenna of a mobile terminal, which adopts a hybrid switching principle of a feeding point 101 and a ground. Specifically, the antenna includes: a radiating unit 20, a feeding point 101, a ground, and Connecting the radiation unit 20 and the grounding line 30 of the ground; further comprising at least two connecting lines connected to the radiating unit 20; wherein one of the at least two connecting lines is selectively switchable to the feeding point 101 or the floating state At least one of the remaining connecting lines may be selectively connected between the feeding point 101 and the ground; and when at least two connecting lines are selectively connected, only one of the at least two connecting lines is connected with The feed point 101 is connected.
在上述实施例中，天线中的辐射单元20、馈电点101及地与现有技术中的移动终端的天线的功能相同，在此不再详细赘述。本实施例的改进点在于改变了辐射单元20与地，辐射单元20与馈电点101之间的连接情况，具体的，在本实施例中，地与辐射单元20之间通过接地线30连接，并且辐射单元20上设置了第一连接线50及第二连接线100，两个连接线并排排列，在连接线与馈电点101及地选择性连接时，满足如下的唯一性：在一条连接线与馈电点101连接时，其余的连接线不能与馈电点101连接。在具体连接时，当其中的一个连接线与馈电点101连接时，该连接线作为馈电线，其余的连接线与地连接作为接地线，或者其余的接地线悬空，此时，没有与馈电点101连接的连接线不再起作用。In the above embodiment, the radiating unit 20, the feeding point 101 and the ground in the antenna have the same functions as those of the antenna of the mobile terminal in the prior art, and details are not described herein again. The improvement of this embodiment is that the connection between the radiating unit 20 and the ground, the radiating unit 20 and the feeding point 101 is changed. Specifically, in the embodiment, the ground and the radiating unit 20 are connected by the grounding line 30. And the first connecting line 50 and the second connecting line 100 are disposed on the radiating unit 20, and the two connecting lines are arranged side by side. When the connecting line is selectively connected to the feeding point 101 and the ground, the following uniqueness is satisfied: When the connecting line is connected to the feeding point 101, the remaining connecting lines cannot be connected to the feeding point 101. When a specific connection is made, when one of the connecting lines is connected to the feeding point 101, the connecting line serves as a feeding line, and the remaining connecting lines are connected to the ground as a grounding line, or the remaining grounding lines are suspended, and at this time, there is no feeding The cable connecting the electrical point 101 no longer functions.

The side of the unit 20 that is not held transmits the signal, thereby avoiding the "catch of death" and improving the signal emission effect.

Corresponding to the position of 1/4 wavelength, the position where the third connection line 40 is set is a position at which the antenna high frequency corresponds to 1/4 wavelength. In the specific setting, it can be set according to the actual situation of the antenna.
在本实施例中，馈电点101设置了选择性开关，即如图1所示的第二选择性开关90，在本实施例中，该开关第二选择性开关90为单刀双掷开关，该单刀双掷开关的不动端与馈电点101连接，动端分别与第一连接线50及第二连接线100连接，即第一连接线50及第二连接线100可以选择性的与馈电点101连接。In this embodiment, the feeding point 101 is provided with a selective switch, that is, the second selective switch 90 as shown in FIG. 1. In the embodiment, the second selective switch 90 is a single-pole double-throw switch.

The point 101 is connected, and the second connecting line 100 is suspended. Of course, it should be understood that the second connecting line 100 can also be grounded. However, since the grounding line 30 of the antenna of the embodiment is located near the second connecting line 100, Grounding or floating the second connection line 100 does not affect the performance of the antenna.
此外，为了改善天线的性能，作为一个优选的方案，在第一连接线50的第二分支线52及第二连接线100上也设置有用于调试天线的频率的调整部件。该调整部件与第三分支线42上设置的调整部件的结构相同，其工作原理也相同，在此不再做详细的描述。In addition, in order to improve the performance of the antenna, as a preferred solution, an adjustment component for adjusting the frequency of the antenna is also disposed on the second branch line 52 and the second connection line 100 of the first connection line 50.
